Is the 1.0 PureTech reliable?

It is a simple naturally aspirated three-cylinder, but with two documented weak points: oil consumption through the piston rings, which Stellantis acknowledges across its entire production (2012-2016), and the oil-bath timing belt it shares with the 1.2. It is only recommended with a full service history, a consumption test and a checked belt.^[1][2][3][4]

Is the Honda e:HEV / i-MMD reliable?

The Honda e:HEV hybrid system (formerly i-MMD) has no serious, widespread faults documented in the sources consulted. The most cited issue is the 12 V battery going flat when the car stands unused and, on the 2.0, a recall for the high-pressure fuel pump.^[5][6]
